"In fact, pipe cleaners are usually made of polyester..."
In my experience it is only the bristled cleaners that are made of polyester, the fluffy ones I use are made from unbleached cotton.
Perhaps you ought shop around?
"I found that is very important to clean the bottom of the bowl, the main cause of sour pipe comes from there."
I would disagree chum, the main cause of a sour pipe is the oft neglected shank, lots of tarry deposits lurk in there. That is where bristled cleaners and alcohol are best used.
